0–100, higher is better. How it is calculated

vmst.io operates as an independent Mastodon server catering to respectful technologists, geeks, and nerds. It provides a federated social networking platform allowing users to participate in the fediverse with features such as trending posts, hashtag exploration, and user profiles. The platform is positioned as a niche community server with a small but active user base, emphasizing respectful and tech-focused interactions. The business model revolves around hosting and community management rather than commercial advertising or monetization. Technically, the site leverages Mastodon version 4.5.0-alpha.1, React for frontend rendering, and is hosted on DigitalOcean with domain registration via 1API GmbH using privacy proxy services. The infrastructure is modern and supports mobile optimization and accessibility at a basic level. Security posture is solid with HTTPS enforced and domain transfer protection enabled, though DNSSEC is not active and security headers are not explicitly detected. Privacy compliance is supported by the presence of privacy and terms of service pages, but lacks a cookie consent mechanism. Overall, the site is trustworthy, professional, and safe for general audiences.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

4 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • High

      No DMARC record found

      DMARC provides email authentication and reporting

      What to do: Add DMARC record: "v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com"

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

The platform targets a specialized audience of technologists and geeks, positioning itself as a respectful and open Mastodon instance within the fediverse. Its competitive advantage lies in its community focus and independence from large commercial social networks. Revenue streams are not explicit but likely rely on community funding or donations as indicated by a funding link. The site maintains transparency with links to source code and status pages, fostering trust. Partnerships or subsidiaries are not evident. Growth indicators include an active user count of 268 monthly active users and ongoing software updates. The ecosystem is primarily open source and community-driven, with no detected advertising or tracking.

Security posture

Security maturity is moderate to good. The site enforces HTTPS and uses domain transfer lock to prevent unauthorized domain changes. However, DNSSEC is not enabled, which could improve DNS security. No explicit security policies or incident response contacts are published, which is a gap for transparency and readiness. No vulnerabilities or exposed sensitive data were detected in the HTML content. The absence of security headers like Content-Security-Policy or X-Frame-Options is a minor concern. Privacy compliance is supported but could be enhanced with cookie consent mechanisms and clearer data protection officer contact information. Overall, the security posture is adequate for a small independent social platform but could benefit from formalized policies and technical enhancements.

Recommendations

  1. Enable DNSSEC to strengthen domain name system security.
  2. Implement and publish a formal security policy and incident response contact information.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Introduce a cookie consent mechanism to improve privacy compliance.
  5. Enhance accessibility features to improve inclusivity and compliance.

Technical notes

Notes

The website uses a modern technology stack centered on Mastodon 4.5.0-alpha.1 and React for frontend rendering. It leverages ES modules and CDN-hosted assets for performance. Hosting is provided by DigitalOcean, a reputable cloud provider. The site is mobile optimized with responsive design and basic accessibility features. SEO is supported by proper meta tags and Open Graph data. Performance is moderate, with no major issues detected. There is no CMS detected, as the platform is custom Mastodon software. Technical risks are minimal but include the lack of DNSSEC and security headers. The site demonstrates good technical maturity for a small independent social platform but has room for modernization in security and privacy features.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
